Supply Cushion Thins as Prices Trend Up on Macroeconomic and Policy Signals

Supply cushions are looking slimmer just as macro and policy currents turn choppy. From production tweaks to regulatory debates and rate expectations, the headline mix is pushing prices gently upward. WTI has inched up to $62.47, while both diesel and gasoline futures are trading higher for the second day in a row.

OPEC+ approved only a modest October increase, about 137,000 bpd, which is far smaller than recent monthly increases. Add in slimmer-than-assumed spare capacity and you’ve got less cushion for unexpected market shockwaves. Saudi Arabia trimmed October official selling prices, a competitive nod to buyers even as China keeps soaking up roughly 0.5 Mbpd for strategic stockpiles, demand that’s unlikely to fade quickly despite Beijing’s longer-term plans to pare refining overcapacity. Overlay the prospect of additional EU/U.S. sanctions on Russia, and the path of least resistance for crude (and by extension diesel and gasoline) has been up, not down.

A third recent supertanker of diesel has pointed toward Europe with large parcels that aren’t unheard of but are unusual in quick succession. Those moves suggest firm Atlantic Basin diesel cracks and a pull on distillate barrels that can ripple back to U.S. racks, especially along the Gulf and East Coasts. At the same time, several U.S. oil and gas companies are trimming staff and capex, tea leaves that point to slower domestic supply growth down the road.

Macroeconomic factors are also at play for demand signals. Inflation watchers expect August core CPI around +0.36% m/m (≈3.1% y/y) and headline near +0.37%, with higher food and energy in the mix. The trend beneath the hood should ease into 2025 as housing and labor contributions cool, but tariffs could keep monthly prints sticky around 0.3%. The Fed is widely expected to cut rates, which typically lowers borrowing costs and can nudge fuel demand higher. August payrolls were soft, and baseline GDP growth for 2025 looks below potential, implying job gains that may not keep the unemployment rate flat. That cooler backdrop could cap demand growth even as equities hit fresh highs.

Global demand isn’t standing still, though. India’s August oil products use rose to 18.7 million tons from 18.3 a year earlier, with gasoline, diesel, and LPG all higher. That steady Asian demand, paired with China’s ongoing stockpiling, helps absorb barrels that might have otherwise weighed on prices.

Policy remains the wild card. Refinery-state lawmakers led by Sen. Mike Lee plan to introduce the “Protect Consumers from Reallocation Costs Act of 2025,” which would bar the EPA from shifting biofuel blending obligations from exempt small refineries onto larger ones. Depending on where the White House lands on handling exempted gallons, RIN demand (and prices) could move significantly. Prohibiting reallocation would likely ease compliance costs for larger refiners and could trim some pass-through at the rack; reallocation would do the opposite. In the near term, uncertainty alone can jolt RIN markets and refining margins, another lever on wholesale gasoline and diesel.
